摘要
The non-random two-liquid (NRTL) equation approach has been used for calculating the activity coefficient and excess Gibbs free energy of the binary alloy system involving two-liquid coexisting phases. The parameters needed for the calculation are the differences of interaction energies (g//1//2-g//2//2), (g//2//1-g//1//1) and non-randomness constant alpha , which are determined by solving NRTL equation with the aid of genetic algorithm. The calculation was carried out numerically for Al-In system. The agreement between the calculated and experimentally determined values of activity coefficient and excess Gibbs free energy is rather good, indicating the validity of the NRTL equation for the description of two-liquid coexisting phase alloy systems.
